Abstract
The utility model discloses a novel small-power LED illumination lamp, which comprises a plurality of LED lamps, a shell for holding the LED lamps, a PCB and a power supply for the LED lamps for lighting; wherein the LED lamps are evenly distributed on the double-sided PCB; and ventholes which are matched with the LED lamps are arranged on the PCB. The illumination lamp has the advantages that: 1) The heat dissipation effect is excellent, the temperature rise is only about 40 DEG C after testing, and light degradation is effectively reduced. 2) Hundreds of LEDs are evenly distributed, point light source is changed into surface light source, and the defect of glare is overcome. 3) The long service life is truly realized which is above 20,000 hours, and is four times as that of the energy-saving lamp and 20 times as that of the incandescent lamp. 4) The structure is simple, the cost is low, and the price is 1/2 as that of the current marketed LED lamp with the same specification. The illumination lamp has the characteristics of energy saving, high efficiency, long service life, no mercury and enormous environmental protection and social benefits.
Description
Technical field
The utility model relates to a kind of LED lighting, is specially a kind of novel low-power LED illuminating lamp tool.Belong to the energy-conserving and environment-protective lighting field.
Background technology
High brightness light emitting diode LED is global flourish at present, with high light efficiency, and cold light source, advantages such as environmental protection and energy saving become the main flow of lighting source of new generation day by day, bring a huge change for world's lighting field.But till today, LED does not still really come into street lamp market.Trace it to its cause, except price was high, some technical difficult points had hindered its development all the time.At first be temperature rise, the heat radiation difficulty causes light decay serious; The 2nd, if adopt several great power LEDs then brightness too converge or some, dazzle is dazzling, is unfavorable for very much people's eyes.For this reason, many scientific circles, enterprise develops multiple LED light fixture and tries hard to improve effect, yet produces little effect so far.
The utility model content
Goal of the invention of the present utility model is for a kind of novel low-power LED illuminating lamp tool being provided, with the response state-of-the-nation call, advancing the application of green illumination.With low-cost design, advance the production of solid cold light source LED of new generation to popularize.And the problems referred to above of solution prior art.
The purpose of this utility model can be achieved through the following technical solutions.
A kind of novel low-power LED illuminating lamp tool, comprise several LED lamps, the shell that holds the LED lamp, pcb board and provide the LED lamp luminous supply unit, described several LED lamps are uniformly distributed on the pcb board of printed on both sides, and pcb board is provided with the passage of cooperated with LED lamp.
Described LED lamp adopts the highlighted light emitting diodes of a plurality of paster encapsulation small-powers (220VAC 20W light fixture is with 4*75=300) combination, because the power of each LED is 0.06W only, be distributed in again on the bigger area, heat is distributed easily, also can effectively reduce dazzle.
The described pcb board back side is provided with the larger areas of copper veneer.
Described passage is a plated through-hole, has the fast characteristics of conduction and heat conduction, not only possesses the circuit linkage function, can also be rapidly the heat of LED be transmitted on the big copper veneer at the pcb board back side to dispel the heat.
The operating voltage of LED is only about 3.3VDC, and because the discreteness of semi-conducting material is bigger, and operating voltage and not all be 3.3V in parallelly uses that electric current that LED that operating voltage is lower than 3.3V flows through just may take place is excessive and damage.At this problem, this patent is taked the 20MA constant-current source circuit of 75 LEDs series connection, is the optimum efficiency design of 220VAC city electric lighting.
The Zener diode of a 3.6V in parallel on described each LED lamp.A plurality of LED series connection are used and are had a bigger shortcoming: as long as there is a LEDs to damage, will scrap whole lamp.And in parallel behind the Zener diode, if one of them LED break,, make be multiplied the service life of light fixture just electric current circulates from zener diode.
Described shell is the aluminium alloy lamp outer casing that possesses the outdoor water-proof design of IP54, and also is provided with the bindiny mechanism that is connected with lamp stand on the shell.
The beneficial effects of the utility model are:
1) radiating effect is outstanding, and temperature rise only about 40 ℃, effectively reduces light decay after tested.2) hundreds of LED are evenly distributed, and the height light source is an area source, overcome the disadvantage of dazzle.3) really realizing the long-life, more than 20000 hours, is 4 times of electricity-saving lamp life-span, 20 times of incandescent lamp.4) simple in structure, with low cost, only be 1/2 of present commercially available same specification LED light fixture price.The design invention of low-power LED lamp makes green light source come into the sub-district street lamp, the parking lot illumination, and the enterprise square, the illumination of greenery patches, gardens becomes possibility.It is energy-conservation, and is efficient, longevity, and the characteristics of no mercury embody its environmental protection, and social benefit is all very huge.
